A-algebra operators, just to remind, there are fundamentally only three of
those, some of the ones typically used are merely derivations of those
three, you can say there are four if TCLOSE is included), that allows a
language implementation that is not only effective for some purpose, but
closed for the desired expressions of that language.

Are the three fundamental ones <AND> <OR> & <NOT>?

If so, is it possible to define a <NAND> such that <AND> <OR> & <NOT> can
be derived from <NAND>?

as in <NOT> A = A <NAND> A

etc.?
